I attended a workshop for phd interviews a couple of weeks ago and basically had two positions I was gunning for. A few days after the workshop I got an immediate rejection from one, but the other has yet to email me almost 2 weeks after. The deadline for accepting/declining offers was supposed to be 10 days and there are 3 people (including myself) going for 2 phd positions. Should I email the guy and ask if I'm out of the running? Would doing so destroy my chances in case the guy sending out the offers has just been extraordinarily lazy?
